Title: Device for producing fiber fusion type multiplexer/ demultiplexer
Inventor: ARIMA TADAO
IPC: G02B6/28
Filed: 1990-01-16
Abstract: PURPOSE:To adjust a taper angle to a prescribed value by inputting the image of a fusion part of two optical fibers, executing image processing to find out the taper angle and controlling a heating range adjusting means by using the obtained taper angle. CONSTITUTION:The optical fibers 10, 20 are heated and fused by a burner 30 and the shape of the fusion part is inputted to an image processor 61 by a television camera 51 to calculate the taper angle. An interval between shielding plates 71, 72 is adjusted by moving pulse stages 73, 74 so that the calculated taper angle coincides with a previously set angle. Since a separation waveguide is determined by the taper angle when a coupling period is fixed, the taper angle can be determined in accordance with the determination of a required separation wavelength. Thus, the tape angle for determining the separation wavelength can be adjusted to an optional value.

Title: Attenuation type phase shift mask and its production
Inventor: YOSHIOKA NOBUYUKI
IPC: G03F1/32
Filed: 1994-01-28
Abstract: PURPOSE:To prevent exposure to regions adjacent to a normal region in the case of continuously executing exposure under movement by forming attenuation type phase shift patterns having patterns smaller than the resolution threshold of an exposure device. CONSTITUTION:This attenuation type phase shift mask has the attenuation type phase shift patterns 2 formed in the prescribed positions on a photomask substrate and attenuation type auxiliary phase shift patterns 3 including the transmitting parts formed in the prescribed positions at the peripheral edges of the attenuation type phase shift patterns 2 and phase shifter parts. Further, these attenuation type auxiliary phase shift patterns 3 have the patterns smaller than the resolution threshold of the exposure device. The images on a semiconductor wafer of the light transmitting the attenuation type auxiliary phase shift patterns 3 are smaller than the resolution threshold of the exposure device and do not, therefore, increase. Further, the light beams transmitting the transmitting parts and the phase shifter parts overlap on each other and since their phases are inverted, these light beams eventually negate each other by interference with each other, by which the light intensity on the semiconductor wafer is weakened.

IPC: B60V1/16
Filed: 1990-01-19
Abstract: PURPOSE:To make peeling difficult to be caused from a bonded part and to prolong the service life of sealing by impregnating nonwoven fabric made of high-strength fiber with rubber or thermoplastic elastomer and. coating this nonwoven fabric. CONSTITUTION:Sealing material is used in the tip part 2 of a finger seal 1. The material of the tip part is constituted by sandwiching nonwoven fabric 4 made of high-strength fiber such as aramid fiber and PVA-based fiber between the thermoplastic elastomer (e.g. polyester system) sheets 3, 5. At this time, the inside of this nonwoven fabric is impregnated with elastomer. Further woven fabric is utilized for ground fabric because the upper part of the finger seal 1 necessitates strength. Thereby a distinct boundary layer is not made between the nonwoven fabric and the coating material. At a time of bonding, dislocation between the materials in this part is made difficult to be caused. In other words, peeling is made difficult to be caused.
